SANITARY EGG BREAKER AND SEPARATOR.

Application filed March 24, 1925.

The present invention relates to an-egg breaker and separator and has for its principal object to provide a device of this nature which is effective, eliicient, and reliable in breaking an egg and separating the contents from the shell.

Another important object of the invention is to provide means for grasping an egg so that the same may be held as desired and while so held the shell may be broken and separated from the contents thereof.

A still further object of the invention is to provide a device of this nature which has an exceedingly simple structure, one which may .be inexpensive to manufacture, and yet be strong, durable, sanitary, not liable to readily get out of order, and otherwise well. adapted to the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing I Figure 1 is an elevation of the improved device embodying theteatures of our invention,

Figure 2 is a plan View of one of the cup shaped members,

Figure 3 is a detail View showing one of the auxiliary aws,

Figure 4: is an edge elevation of the releasing slide bar, and

Figure 5 is a detail perspective view of a guide plate.

Referring to the drawing in detail it will be seen that A designates a pair ot main operating jaws pivoted together intermediate their ends by a bolt 5 or the like so as to provide short arms 6 and long arms or handles 7 having a spring 8 interposed therebetween tor normally holding the short arms 6 toward each other. A pair of auxiliary jaws or levers B are pivoted together intermediate their ends by a bolt 9 so as to provide short arms lO'and relatively long arms 11'. The long arms 11 are provided with spaced extensions 12. The short arms are pivoted as at 13' to theshort arms 6 in a substantially toggle formation so that the spring 8 normally holds the extensions Serial No. 17,935.

12 toward each other. A pair of cups Gare pivotally engaged on the ends of the extensions 12. Each cup C includes a rim 14 having pintles 15 projecting therefrom and gers 17 which are attached to the rim 14 and extend along the bowed strips 16 in spaced relation thereto and terminate a distance from the bottom of the cup as is clearly seen in both Figures 1 and 2. a

The rims 14 of the cups C are provided w th slots 18. Bowed spring members 19 are mounted within the rims 14 having one end attached thereto as at 20 while the other ends are oitset to form ears 21 projecting through the slots 18. i

A bar 22 is provided with a longitudinally extending slot 23 for receiving the bolt 9 and a guide plate 24 tends to hold this slide bar in place on the bolt and alongside the p voted portions of the levers B. Wires 25 are connected to one end of the bar 22 and to the ears 21 of the spring members 19. The other end of the bar 22 is provided with a-finger loop 26. One'longitudinal edge of the bar 22 is provided with ratchet teeth 27. Leaf springs 28 are attached to the arms 11 of the levers B and engage the longitudinal edges of the bar 22 and tend to hold this .bar in alignment with the bolts 5 and 9.

997m of the springs engage the ratchet teeth The intermediate portions of the springs 19 are provided with cutting teeth 30. It will thus be seen that when the bar 22 is pulled downwardly in Figure 1, the springs 19 will be drawn toward the centers of the rims 14 of the cups C for severing the shell of an egg as will appear. One of the rims 14 is provided with a pair of cars 32 while the other rim is provided with a single our 32 to be received therebetween in order that a pivot pin 33 may be passed therethrough, thus pivoting the two cups together. i

This device is always held open, that is the cups are held swung away from. each other by the spring 8. hen the device is to be used for holding an egg which is to be tried, grasp the handles 7 in the hand. Place the egg so, that the ends thereof will be disposed in the cups C as the handles 7 are moved toward each other and thus the egg isheld securely over the fryingpan. Place a finger in the loop 26 of slide bar and pull the same downward toward the handles 7 until springs 19 with'their sharp teeth 30 cut through the shell of: the egg, then release the handles 7 slowly, and the egg will gently drop into the frying pan, or into any other receptacle that requires an unbroken fresh egg. One of the springs 28 will continue to hold the side bar =and thus the springs l9w-ill'conti1me to hold the egg shell in the cups C until a slight pressure is made with the finger against the slide bar for releasing the springs-28 at which time the egg shells are free to drop intoaretuse can or the like.

To use the device in handling soft or-hard boiled eggs, proceetbin the same manner as previously explained in handling anegg-to be tried, or for any other usethat afresh egg is to be used,'but with the exception that when the hard or sott boiled egg is taken out of the boiling water, it is cracked by squeezing'the handles- 7. If it be -a sot't boiled egg, the' same' should be heldover the receptacle, letting'whatever part of the that is loose to fall out, andwhatever re 1 mains in the shell, cups'C will'continueto hold with the shell hal'vesthereot' tintilt-he contents thereof areremoved with a spoon or other utensil. The's'hells may then be removed'as previon'slyindicated. In handling a hard boiled egg,atter' taking it from the boiling water, squeeze the handles 7 toward each other and then release the handles fully and remove thecontents of both halves of the shells *locate'din the cups with a spoonor other utensil, 'andproceed to drop the egg shell as previously indicated. This device will'separate'the whites from the yolks in a fresh egg by picking up the egg as previously explained, an'd squeezing the handles 7 so as to crack the eggand then by releasing the handles slightlywhich will open the cups from each other about (meapiarter of an inclifanfd giviiig a twisting motion from right tole'tt,=the'white will loosen from the yolk and'fiow outslowly, leaving the yolk in the shell'wl'iich can then be slowly dropped in another receptacle, the shells being dropped in the'usual man ner, above explained.
